Passive skills replaced Traits during late game development in 2011. Many Traits were simply changed to passive skills, but some are all new. See the Witch Doctor traits page for a full list of those passives.

The Witch Doctor's skills and skill trees were first seen at BlizzCon 2008, with only a few skills enabled and many showing nothing more than vague descriptions in the skill tree. The listing was fleshed out at Blizzcon 2009, but most of his skills, especially the summoning ones, remained NYI. The current information was revealed at Blizzcon 2010, with the passive skills removed (see the Witch Doctor traits and a near-final skill listing.

A large number of the higher level WD spells have still never been shown publicly, in contrast to the skills of the Wizard and Barbarian, almost all of which have been shown off.
